Create a synthetic monitor status rule

Within the Synthetics UI, create a Monitor Status rule to receive notifications based on errors and outages.

The Filter by section controls the scope of the rule. The rule will only check monitors that match the filters defined in this section. In this example, the rule will only alert on browser monitors located in Asia/Pacific - Japan.

Conditions for each rule will be applied to all monitors that match the filters in the Filter by section. You can choose the number of times the monitor has to be down relative to either a number of checks run or a time range in which checks were run, and the minimum number of locations the monitor must be down in.

The Rule schedule defines how often to evaluate the condition. Note that checks are queued, and they run as close to the defined value as capacity allows. For example, if a check is scheduled to run every 2 minutes, but the check takes longer than 2 minutes to run, a check will not run until the previous check has finished.

You can also set Advanced options such as the number of consecutive runs that must meet the rule conditions before an alert occurs.

In this example, the conditions will be met any time a browser monitor is down 3 of the last 5 times the monitor ran across any locations that match the filter. These conditions will be evaluated every minute, and you will only receive an alert when the conditions are met three times consecutively.

Extend your rules by connecting them to actions that use the following supported built-in integrations.

After you select a connector, you must set the action frequency. You can choose to create a summary of alerts on each check interval or on a custom interval. For example, send email notifications that summarize the new, ongoing, and recovered alerts each hour:

Alternatively, you can set the action frequency such that you choose how often the action runs (for example, at each check interval, only when the alert status changes, or at a custom action interval). In this case, you must also select the specific threshold condition that affects when actions run: the Synthetics monitor status changes or when it is Recovered (went from down to up).

You can also further refine the conditions under which actions run by specifying that actions only run when they match a KQL query or when an alert occurs within a specific time frame:

Use the default notification message or customize it. You can add more context to the message by clicking the icon above the message text box and selecting from a list of available variables.

The following variables are specific to this rule type. You an also specify variables common to all rules.
